  2. 1. Laser Diagnostics in Combustion - Elastic Scattering and Picosecond Laser-Induced Fluorescence

    Author : Frederik Ossler; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spray; Picosecond laser; Streak camera; Time resolved; Fluorescence lifetimes; 3 – D flow imaging; 2 - D lifetime imaging; Pressure; Temperature; Hydrogen atoms; Oxygen atoms; 3-pentanone; Acetone; Lorenz-Mie theory; Aerosol; Fysicumarkivet A:1999:Ossler; Scattering; Fysik; Physics; Polycyclic aromatic hydrocarbons.;

    Abstract : Elastic scattering and the Lorenz-Mie (LM) theory in particular is used for the characterization of sub-micron- and micron-sized droplets of organic fuels in sprays and aerosols. Calculations on the Lorenz- Mie theory show that backward-sideward scattered visible radiation can be used for unambiguous detection of ensembles of homogeneous droplets of organic substances with diameters around 1 micrometer (size parameter between 2 and 6).

  4. 2. Development of Laser-Induced Fluorescence for Precombustion Diagnostics in Spark-Ignition Engines

    Author : Hans Neij; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DME; fuel tracer; Laser-induced fluorescence; 3-pentanone; acetone; residual gas; dimethyl ether; water vapor; Fysicumarkivet A:1998:Neij; Fysik; Physics; ion current;

    Abstract : Motivated by a desire to understand and optimize combustion in spark-ignition (SI) engines, laser techniques have been developed for measurement of fuel and residual gas, respectively, in the precombustion mixture of an operating SI engine. The primary objective was to obtain two-dimensional, quantitative data in the vicinity of the spark gap at the time of ignition. READ MORE

  5. 3. X-ray structure analysis of short-chain dehydrogenases/reductases

    Author : Jordi Benach-Andreu; Karolinska Institutet; Karolinska Institutet; []
    Keywords : crystal structure; short-chain dehydrogenases reductases; Drosophila alcohol dehydrogenase; catalytic reaction mechanism; Comamonas testosteroni 3[beta] 17[beta]hydroxysteroid dehydrogenase;

    Abstract : X-ray crystallography and site-directed mutagenesis were used to better understand the structure/function relationships in the family of short-chain dehydrogenases/reductases (SDR). This group of enzymes constitutes a protein family with at least 60 members with highly diverse functions in pro- and eukaryotes. READ MORE
